g UNITED stmrEs1 PATENT LEGER Diss, 0E oRIsKANY, NEw YORK.

LOCK.

Specification of Letters Patent No. 26,659, dated January 1866.ll "1 i. l,

To all whom 'it may concern:

Be it known that I, LEGER Diss, of Oriskany, in the county of Oneida and State of New York, have invented a new and useful Improvement in Locks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawing, forming part of this specification, in the several figures of which similar characters of reference denote the same part.

Figure l is a plan view of the lock `with the outer plate removed. Fig. 2 is a view of the same when unlocked, by using the key. F ig. 3 isa view when unlocked `from the inside without the'key with the stop holders removed. Fig. 4, is a vertical section on line w m.

The nature of the invention consists in having an arm or lug on the barrel through which the handle passes, which ts into a cavity in the bolt, so that the bolt is moved by turning the handle. The bolt having also a spring to cause it to fiy back after the handle is released, and is held in place by a stop catching against a projection at the lower end of it. This stop is divided into two sections, the back one into which the point of the key goes, projecting over the front one slightly, so as Vto allow the turning of the key to move bothsections down. There is also a series of stop holders turned by bits on the key and so arranged that when the key is at an angle of ninety degrees their openings are all `opposite to eachother s0 as to allow the stud on the stop pass vthrough into their large opening and the key turning farther around their openings close again thus holding the stop down, there is also a spring on each side of these holders to keep them in position.

The front section of the stop can be moved down independently of the back section, which is done by a lever passing through the plate of the lock to the inside of the door. This lever presses against a projection on said section of the stop and moves it down, thus allowing the bolt to be turned back from` the inside without turning or using the key at all. This front section of stop has a spring under it to force it up; into place as soon as the lever is released. There are also guides on each side of the stop between which it moves.

In opening the door `from lever L-, extending throughthe `plate ofthe theioutside the` key is inserted and turned, and `at"`theksam`e E time that the point ofthe gf'keyfis moving f the stop A down, thebits `on thedrey;.turnl 7011 the stop holders `I-I, in 3 positionto 1b1ing3f `3 their opening opposite: eachother.` forlllthe` i admission of stud d, on `stop A, and `.when
